IMPROVEMENT IN SLEDS.

Specification forming part of Letters Patent No. 157,823, dated December15, 1874; application filed October 15, 1874.

To all whom it may concern:

Be it known that I, WILLIAM H. HELM- BOLD, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented an Improvementin Ghildrens Sleds, of which the following is a specification:

My invention relates to the combination of pushing-shafts, levers, andconnecting-bars and braces, with the sides of the sled for propellingit, as hereinafter fully described.

In the accompanying drawings, Figure 1 is a plan view of my improvedsled. Fig. 2 is a side elevation of the same.

Like letters of reference in both figures indicate the same parts.

A A are the sides or runners, and B the top, having a foot-rest, C. I

It may also be provided with any suitable seat.

To each side A is connected a vertical lever, D, by means'of thefulcrum-pin a. To the lever is jointed the pushing-shaft E, having apointed end, b, which should be shod with steel, so as to stick in theground when the lever is pulled back to give the forward motion to thesled. The shaft is hung on the pivot c, between one end ofthe bar F andthe brace Gr, the other ends of the bar and brace being connected,respectively, with the lever by means of the screw or bolt d and thefulcrum-pin a.

By this mode of connecting the shaft E to the lever, great strength issecured.

There are holes e in the levers D, pushin shaft E, bai; F, and brace G,for varying their connection, if desired, to give more or less leverage.At each side of the sled there are vertical slots f in the top B, forthe lateral guiding of the levers D and shafts E.

The operation is as follows: Each lever is thrown into its forwardposition, as shown clearly in Fig. 2, and pushed backward into theposition represented at the opposite side of the sled. The levers,ope-rating independently of each other, are moved simultaneously in thesaine direction when the sled is to be propelled straight forward. Whenit is required to vary its direction, it is steered by varyin g theirmovements.

I claim as my invention- The combination of the levers D, pushingshaftsE, bars F, and braces G with the sides of the sled, substantially as andfor the purpose set forth.
